Example not compiling in net5.0 project

molotch commented 2 years ago

Just starting out F# and am trying the examples.

This example fails to compile with the error:

error FS0597: Successive arguments should be separated by spaces or tupled, and arguments involving function or method applications should be parenthesized

printfn "%c" str1[1]

If you add a dot (.) between the string literal and the array notation it works as intended, i.e. "str1.[1]". Is there's a difference depending on what F# version you're using?

being able to remove the "." from the indexing syntax is new to F# 6

I think this should just be closed. It's not a doc bug and .NET 5 is out of support.
